    new-calendar-page: add callback for new calendar color chooser
    
    The color chosen in the new calendar page is currently ignored
    when creating a new calendar, as described in #681.
    
    Added a callback similar to that used for the name text entry,
    allowing new calendars to be created with the chosen color.
    
    Closes https://gitlab.gnome.org/GNOME/gnome-calendar/-/issues/681
